Cactbot can print large, bolded instructions directly to your screen the milisecond an ability is telegraphed (and sometimes before it's even telegraphed clientside), with customized text that doesn't just label the ability, but gives you personalized instructions on how to solve the mechanic. This isn't even in the same universe as traditional shotcalling in some encounters.

It can also be used to draw a timeline on your screen, showing you exact times until upcoming abilities come out.
